Antispam, or inconvenience?

Today I found out that my own ISP’s (Fastweb) mailserver got into a spam blacklist. I can understand how it happened, since Fastweb has a limited pool of public IPs and everything is behind a massive NAT. I checked the web page of the organization that blacklisted the IP and noticed they want you to pay a fine of $50 to get removed. I can understand that perhaps this is due to spammers being on a rampage around, but those guys just blacklisted an entire ISP’s mail server because they didn’t bother to check. And now you have to pay also to remove yourself? Bah.

What’s worse is that my own ISP doesn’t care a lot about such issues. But that’s another matter entirely.
